UK popstar Jessie J took to the stage at the V Festival in Berkshire, England.

The singer recently wowed the audience at the Olympics closing ceremony and has racked up huge album sales since. In fact, all the performers at the London ceremony saw spikes in record sales, according to reports.

Not that Jessie J has anything to worry about ... the 24-year-old is on top of the charts with her single, Price Tag.

JJ took to Twitter after the gig, writing: "Perfect way to end my 2012 Summer Shows in 30 degree heat dancing and singing with 20k people! Thank you Newbury for an amazing day :) x"
